With the bolt head to the bottom, the spring just barely rubs across it.
And I'm procrastinating engine reassembly a little longer by polishing the timing cover.
An angle buffer and some Mother's Mag and Aluminum polish will shine that right up.Well, maybe polish was a misnomer. Since I know of no short cuts for real polishing, calling it a buffed up thorough cleaning would be more accurate. I figured my time post surgery would be better spent with actual engine reassembly, so I skipped the long emery paper drill and just went straight to my buffing wheel. So be it. I might send it out for pro polishing if I come across a good place.
